About alignments and sextant

This holiday season, during which we will gladly return for a few days to traditions, inspires me to rethink the traditions of an activity that is dear to us : navigation.
Not one of our illustrious predecessors, royal marine, discoverers of distant lands, privateers, pirates or honest merchants, no. I want to mention one that concerns us for over half a century : yachting. Especially to the attention of our friends who are sailors born in 70-80, who discovered the navigation from the years 90, period of the emergence of GPS on board our yachts.
I, who is constantly adding a website and a blog on the intricacies of computing onboard, all these tools that bring us our position a few meters, the weather in eight days, the depth of water under the keel, the time that it will tack to take advantage of favorable wind shift, and how much additional information is available in three mouse clicks, I never forget how I learned to navigate.

The basics of navigation.

I think having the chance to be born in the 50, and then to discover boating in the 70, with a sail thread in hand (whipping twine) and a rigid chart on my knees. I spent weeks learning to find myself on the chart and the landscape around me by practicing this nautical basic : call number steering by alignment.

Good trainee and highly motivated, I assumed the cruise, crossed my beginner's "Cape Horn", Passage of the Teignouse, Raz de Sein, Raz Blanchard, practicing a rustic but effective navigation, this other basic the dead reckoning. It is understood that, regarding the number of hours spent at the chart table, better not be seasick, or provide a bucket nearby post !

Yachtsman more informed, I traveled to sail without an engine, with any kind of boats our beautiful Atlantic coasts, with a sounding line, a log line, and weather forecastss from France Inter and BBC Radio4. Even in the thick fog in the Channel, I do not recall ever having to ask anyone's help to land or take a boyage. Anyway, even though I was equipped with a VHF – what luxury – I had not learned to use it, can you imagine !

Became a professional yachtman, I had no other choice, to perform offshore cruising, than learning how to use a sextant. Ah, the celestial navigation ! This final basic religiously addressed, sure access to an elite, a small circle of "Moitessier", of "Tabarly", about « Damien »… The only instrument for cruising 4000 nautical miles and land straight to the select landing, always with great anxiety in the hours preceding, and a great surprise to discover the right place front of the stem, not another one.

Electronic era

I ended up learning how to use all the beautiful toys that I met during my sailings : GPS, Radar, ChartPlotters, SSB… Then I sold it,I installed it, I trained users. Finally, more recently computers have boarded our boats : laptops, light, cheap second hand, with software developed to facilitate our navigator's life. The rest you know that.

I fear that today many « youth » yachtsmen can not live without it. Traditional sailing schools, essential in my day, do hardly recipe, or the charter school disguised as a sailing « Level Zero to Astro Navigation » one week ! Who would still be able to port entrance only sailing, in engine failure, without calling a tow by VHF ? Which can still cross the Channel with dead reckoning, batteries went flat, and landing to Falmouth steering the right side of the Lizard ?

Far from me to want to criticize, denigrate, still less to preach. I am simply finding more than since ten years the advent of the electronic equipment has led many beginners yachtsmen to make them an extreme confidence, and forget the basics of navigation that I had, for my own, chance to gain.

The homecoming

So in this holiday season or traditions is to offer gifts, indulge yourself with a book that tells you these famous fundamental, i.e. : Glenans Sailing Manual, or Navigation on the high seas, by Olivier Stern-Veyrin, exhausted but still found on eBay (and also looked very). Visit navastro.fr or immerse yourself in the « fundamental formula of celestial navigation » from this page Francis Lonchamp. Then at Spring, try to turn your first GPS navigation computer off. You will see, this will be a homecoming for saving, for your viewing pleasure as for your batteries relief !

Merry Christmas and happy New Year, see you next year !
